- WebStart
- WebStart is a tool for application distribution and version control.
- Developer only has to install the application on the SERVER.
- WebStart only requires the clients to have Java.
- Neither NeXtMidas nor the application itself have to be installed on the client machines!.
- First Use:
- When the user clicks a JNLP (Java Network Launch Protocol) link in a web
page, Java WebStart downloads the necessary application files, which are
zipped up in a JAR (Java Archive) file, and launches the application.

- The application then runs as if it was a normal Java application installed
on the local system.
- Subsequent Uses:
- Java WebStart maintains a local cache of the application files.
- When the application is run, WebStart checks to see if the local copy is
up-to-date.
- If a newer version is available on the web server, WebStart will download
it and launch the new version.
- If the local copy is up-to-date, WebStart skips the download and runs the
local copy.
- If the server is unavailable, WebStart can still run the local copy (it
just skips the up-to-date check when the server is unavailable).
